What if the real risk in the psychedelic renaissance isn’t the medicines themselves?

What if the deeper tension is what happens when human beings regain direct access to experiences that cultures have spent centuries trying to regulate?

Across history, cultures have developed ways of managing direct encounters with the sacred.
Sometimes through religion. Sometimes through law. Sometimes through medicine.

In a recent conversation on My Psychedelic Story, Micah Stover described psychedelic work as “metaphysical heart surgery.”  The phrase immediately resonated with me. For years, in my own work and reflection, I have often thought about these experiences in slightly different terms. Through the lens of Functional Systems Regulation Theory (FSRT), I have come to see many psychedelic experiences as a form of what might be called cosmic surgery. Not surgery in the literal sense, but in the way these experiences appear to reach into the deepest layers of the human system, altering perception, reorganizing meaning, and sometimes reshaping the architecture of identity itself.

If Micah’s framing highlights the emotional center of the human experience, cosmic surgery speaks to something broader. These medicines do not simply touch the psyche. They often reorganize the relationship between the individual mind and the wider systems within which it exists. Identity, memory, trauma, meaning, culture, and even one's sense of connection to the cosmos itself can all be placed into motion. From the perspective of Functional Systems Regulation Theory, this raises a deeper question about the role psychedelics may have played throughout human development.

Long before we had clinical language for trauma, nervous systems, psychotherapy, or integration, human beings were already encountering altered states of consciousness that expanded perception, deepened emotional processing, and accelerated meaning making. Increasingly, anthropologists, neuroscientists, and historians of religion are revisiting the possibility that entheogenic plants and compounds may have contributed to the emergence of symbolic language, mythic thinking, and complex culture. 

In other words, these medicines may not simply be tools for healing. They may have helped shape the very cognitive architecture that allows human beings to reflect, imagine, and construct meaning about their lives.  And that possibility reframes the current psychedelic renaissance in a fascinating way. Because the question may not simply be,  how do we regulate psychedelics?  It may also be, how have cultures historically attempted to regulate access to direct spiritual experience?

Cosmic Surgery and the Biology of Transformation

If the language of cosmic surgery sounds poetic or metaphorical, modern neuroscience is beginning to reveal that something structurally similar may be occurring inside the brain.  Many psychedelic compounds share a common pharmacological pathway. Classic psychedelics such as psilocybin, LSD, and DMT exert their effects primarily through activation of the serotonin 5-HT2A receptor in the cortex. These receptors are densely expressed in brain regions associated with learning, perception, emotional processing, and meaning making, particularly within the prefrontal cortex and associative cortical networks. When psychedelics activate these receptors, the brain appears to temporarily enter a state of enhanced plasticity, allowing previously rigid patterns of neural organization to loosen and reorganize.

Research has demonstrated that psychedelic compounds stimulate dendritic growth, increased synaptic density, and enhanced neural connectivity, processes associated with learning and adaptation (Ly et al., 2018; Vargas et al., 2023). These effects appear to be mediated through intracellular pathways involving brain-derived neurotrophic factor (BDNF) and mTOR signaling, both of which regulate synaptic formation and neural plasticity. In practical terms, this means the brain may temporarily become more capable of reorganizing how it processes experience and meaning.

From the perspective of Functional Systems Regulation Theory, this is deeply significant. Trauma, identity structures, and habitual patterns of thought often stabilize through repeated neural firing patterns over time. These patterns become the homeostatic organization of the nervous system, shaping perception, behavior, and emotional response. When psychedelic compounds increase neural plasticity through 5-HT2A receptor activation, the brain may briefly regain access to a level of developmental flexibility that is typically far less accessible in adulthood.

When this happens, the mind is no longer confined to the story it has been repeating. It becomes capable of reorganizing the systems through which that story was constructed. From an FSRT perspective, this is where the metaphor of cosmic surgery begins to make sense. The intervention is not occurring only at the level of mood or symptom relief. It is occurring at the level of systems architecture.

Ibogaine and the Interruption of Entrenched Patterns

Among psychedelic compounds, ibogaine occupies a particularly unique place in both pharmacology and experiential reports. Unlike many classical psychedelics that primarily act through serotonin pathways, ibogaine interacts with multiple neurochemical systems simultaneously, including serotonin, dopamine, NMDA glutamate receptors, and the brain’s opioid receptor systems. Its primary metabolite, nor-ibogaine, remains active in the body for extended periods, influencing mood regulation and neuroplasticity long after the acute experience has ended. This pharmacological complexity may help explain why ibogaine has drawn increasing attention for its potential role in interrupting entrenched patterns of addiction and trauma.

Research suggests that ibogaine administration can produce rapid reductions in opioid withdrawal symptoms and cravings, effects that may be partially mediated through its modulation of the mesolimbic dopamine system and opioid receptor pathways (Alper et al., 1999; Mash et al., 2001).  Animal studies have also demonstrated that ibogaine increases expression of glial cell line-derived neurotrophic factor (GDNF) in the midbrain, a protein associated with neural repair and stabilization of dopamine circuits involved in addiction (He et al., 2005).  From a neurobiological perspective, this suggests that ibogaine may not simply suppress symptoms of addiction. It may temporarily reorganize the regulatory systems through which addictive behaviors are maintained.

Experientially, many individuals report that ibogaine sessions involve an unusually structured form of introspection. Rather than producing the free-flowing perceptual distortions often associated with serotonergic psychedelics, ibogaine experiences frequently unfold as a highly ordered review of autobiographical memory, sometimes described as watching one's life play out in rapid sequence.

Researchers have described ibogaine as producing a waking dream state, where vivid dreamlike imagery unfolds while the individual remains fully conscious. From the perspective of Functional Systems Regulation Theory, this experiential pattern is particularly intriguing. Trauma and addiction often become stabilized through deeply ingrained behavioral loops and narrative identities that the nervous system repeats automatically over time. These loops represent powerful forms of homeostatic patterning, where the system organizes itself around familiar regulatory strategies even when those strategies are destructive.

Ibogaine appears capable of temporarily interrupting those loops. By simultaneously increasing neuroplasticity while facilitating intense autobiographical processing, the medicine may allow individuals to observe the patterns that have shaped their lives from a vantage point that is normally inaccessible. For many practitioners working in this field, different medicines seem to call to them in different ways. In my own work, ibogaine is the medicine I feel most drawn toward, precisely because of the depth with which it appears capable of revealing and reorganizing the systems that shape human suffering.

The Narrative Self and the Default Mode Network

Another mechanism that may help explain psychedelic experiences involves the Default Mode Network (DMN). The DMN is a network of interacting brain regions that becomes active when the mind engages in self-referential thinking. It is closely associated with autobiographical memory, narrative identity, rumination, and the ongoing maintenance of our sense of self. Under normal conditions, this network helps organize experience into a coherent internal story about who we are and how our lives fit together.

However, psychedelic compounds appear to temporarily reduce the stability and dominance of the Default Mode Network. Neuroimaging studies have demonstrated reduced activity and connectivity within this network during psychedelic states (Carhart-Harris et al., 2012). When the DMN quiets, the rigid narrative structures that normally define identity can temporarily loosen. As these structures soften, individuals may experience phenomena such as ego dissolution, expanded perspective, emotional catharsis, novel associations between memories and ideas, and feelings of unity or interconnectedness.

From a therapeutic perspective, this loosening of identity structures may allow individuals to revisit traumatic memories, challenge deeply entrenched beliefs, and develop new interpretations of their experiences. The temporary disruption of rigid narrative patterns can create a window in which previously fixed meanings become more flexible and open to reorganization.

From a Functional Systems Regulation Theory perspective, something deeper may also be occurring. When the narrative structures that organize identity temporarily soften, the nervous system may gain access to deeper layers of regulation and meaning making that are normally filtered through the narrative self. In this sense, the individual is not simply revising a story about their life. For a brief period, they may step outside the system that generates the story itself.

The Cultural Regulation of Spiritual Experience

Throughout history, many societies appear to have gradually restricted or eliminated widespread access to psychoactive sacraments. In many traditions, direct mystical experience became mediated through institutions such as organized religion. Instead of encountering the sacred directly, individuals were encouraged to encounter it through doctrine, clergy, ritual hierarchy, and interpretation. From a Functional Systems Regulation Theory perspective, this shift has profound implications.

Direct encounters with awe, transcendence, and altered states can destabilize rigid belief systems and social hierarchies. When individuals access powerful experiences of meaning and interconnectedness directly, the authority structures that traditionally interpret those experiences may become less necessary.

Over time, cultures often respond to this destabilizing potential by centralizing spiritual authority.

Belief replaces experience.

Dogma replaces encounter.

Interpretation replaces revelation.

The Delusion of Comfort and the Return of the Sacrament

Functional Systems Regulation Theory proposes that human systems tend to organize themselves around patterns of stability, even when those patterns are rooted in distress. Over time, these patterns become what FSRT describes as homeostatic patterning. The nervous system learns what is familiar and begins to treat familiarity as safety, even when the underlying pattern may be painful or maladaptive. At both the individual and cultural levels, this process often produces what I have described as the delusion of comfort. A system becomes organized around avoiding the very experiences that might lead to its transformation.

Psychologically, this can appear as the avoidance of grief, trauma, uncertainty, or existential questioning. Culturally, it can manifest as rigid ideologies, institutional belief systems, or social structures that discourage direct encounters with mystery and the unknown. Psychedelic experiences challenge these patterns in a unique way. They temporarily bypass familiar regulatory strategies of the mind.

Defensive narratives soften.

Identity structures loosen.

Emotional material that has long been held outside awareness may begin to surface.  From the perspective of the nervous system, this can feel destabilizing.

But from a systems perspective, this destabilization may be exactly what allows transformation to occur. Systems that have become rigid often require a temporary increase in uncertainty in order to reorganize into more adaptive forms. In this sense, psychedelic experiences do not simply introduce new insights.

They may temporarily interrupt the homeostatic patterns through which identity and culture maintain themselves. This is where the idea of cosmic surgery returns.

Not because the medicines remove something from the system. But because they allow the system to reorganize itself around deeper levels of coherence and meaning.

The psychedelic renaissance may therefore represent something larger than the reintroduction of powerful therapeutic tools. It may represent the return of the sacrament. And when the sacrament returns, it does not simply transform the individual. It begins to transform the system itself.

The medicines were never the threat.

The threat was always what happens when human beings remember they can encounter the sacred directly.
